"THE USE OF RAINFALL CHARACTERISTICS IN DEVELOPING METHODS FOR REDUCING WET WEATHER ACCIDENTS IN TEXAS"

This report was developed to provide a basis for further study of wet weather accidents. A method evolved to determine the percent of time the pavement is wet, leading to the development of a wet weather accident rate. A study of rainfall intensities was made. The average 85the percentile rainfall intensity of eighteen weather stations was found to be 0.14 inches per hour, based on measurements of a one-hour duration. When extrapolated to a five minute duration, the 0.14 inch per hour intensity was found to be increased to 0.50 inch per hour. The 0.50 inch per hour intensity was termed the "Average 85th Percentile Rainfall intensity Based on a Five Minute Duration" and is suggested for use in design for skid resistance studies.
